Meanwhile, the mold of the invention can apply certain pressure onto the pouring material so as to improve the compactness of the pouring material.
Description
Technical field
The present invention relates to a kind of mould of building, particularly a kind of be used for process nozzle protective material build mould and with the method for its cast.
Background technology
No matter be the single fire mouth, or many burners water coal slurry pressure gasification technology, water-coal-slurry and pure oxygen all spray into the gasification furnace combustion chamber and react by process burner is parallel.About 1300～1500 ℃ of gasification furnace internal temperature, medium is the mixture of high-temperature slag and gas, main gas componant is H
2, CO, CO
2, SH
2, SO
2Deng, because the influence of bad working environments such as high temperature heat radiation, slag erosion, high-temperature gas corrosion in the gasification furnace causes the be full of cracks of burner outer oxygen nozzle hydroecium, problems such as corrosion cracking appear in burner coil pipe, outer oxygen pipe, influence the cycle of operation.
By burner head, outer coils are protected; can play and prolong the burner purpose in service life; protective material generally uses exotic materials such as alumina hollow ball pouring material; requirement is built evenly fine and close; cylindricity and concentricity are little; smooth surface all covers the fragile surface of burner.
Former builds in the process, and wooden or iron sheet commonly used rolls simple die, has following problem:
1, build difficulty, need to adjust repeatedly, repeatedly build the reconditioning moulding, difficulty of processing is big, wastes time and energy;
2, scale error is big behind the forming materials, and cylindricity and concentricity are poor, and is bad with cooperating of gasifier nozzle chamber, damages LIFT when burner is installed easily, and the damage of burner is quickened in the gas backstreaming of burner chamber in running;
3, build became uneven, material internal is evacuated ventilative, does not reach the purpose of protection burner.
4, poor surface smoothness, the front/rear end moulding is bad, and not anti-washing away after use a period of time, with ash slag sintering, when pulling down burner, easily broken coil pipe.
Summary of the invention
The purpose of this invention is to provide a kind of be used for process nozzle protective material build mould and with the method for its cast.This mould is according to process burner appearance and size designing mould, and this mould should have certain intensity, can avoid the distortion in the process of building, and imposes certain pressure to building material simultaneously, improves density, general available metal material or other hard non-metallic materials.
The technical scheme that the present invention takes is:
A kind of mould of building that is used for process nozzle protective material; comprise the cylindrical shape formwork that combines by two or polylith arc; the circular port at cylindrical shape formwork two ends is respectively equipped with front apron and backboard, and the cylindrical shape formwork is provided with cast gate and a plurality of adjustment bolt.
Connect by bolt between the described arc.
Described cast gate is oval, is provided with two.
Described backboard is that two semicircular plates are formed, and center drilling is the outer oxygen external diameter of pipe size of burner.
Described front apron all links to each other with the cylindrical shape formwork by clamp with backboard.
Use the described method that mould is built of building that is used for process nozzle protective material: will build the cooling water coil outside that mould is fixed on process burner, utilize the adjustment bolt to adjust the concentricity of building mould and burner, install front and rear baffle, pour into refractory material from cast gate, and the casting mold outer wall knocked, guarantee that watering material feeding builds evenly; Dry 4-6 hour, or feed steam toward cooling water coil and heat to 60-80 ℃, dry two hours, after can pull down casting mold.
Beneficial effect of the present invention is:
The time that can effectively save the casting craft nozzle protective material is with artificial; reduce and build difficulty; can improve the process nozzle protective material pouring quality; appearance and size after better control is built; improve surface smoothness, prevent off-centre and ellipse, when having avoided the dismounting process burner; the protective material that causes because of scale error or the damage of burner coil pipe reduce maintenance cost.Be provided with a plurality of adjustment bolts, can adjust centrad and cylindricity arbitrarily.
Can make and build behind the forming materials more closely knitly, prevent to collaborate, effectively alleviate high-temperature gas process burner is corroded, improve the burner cycle of operation, save the process burner maintenance cost and for changing the operating cost that process burner increases.
Can save and build material, rational structure of the present invention and feeding manner, the material unaccounted-for (MUF) of having avoided other mode of building to bring.
Economic benefit: with 1150 ton of four nozzle gasification furnace of coal feeding amount every day is example, and process burner damages one, and the back that needs to stop is all changed, and four process burners changing are all keeped in repair, about 6.5 ten thousand yuan of every burner maintenance cost.While increases operating cost about 150,000 yuan, about 240 tons of underproduction synthetic ammonia because of system shutdown.By improving the pouring quality of process burner, can effectively improve the cycle of operation, the burner life cycle extended to 90-110 days by about 60 days, can reduce every year because of burner damages stop frequency 2-3 time, avoided above loss, increased benefit more than 1,000,000 yuan.And can reduce labour cost and the Master Cost that protective material is built.
